Ferry Ticketing System

Hi
Actually i try to do this programming but i have some problems.
I'll become thank you if help me to fix it.
It is a simple Ferry Ticketing System with below conditions :

FERRY TICKETING SYSTEM
A small ferry company has just purchased a computer for its new automated ticketing system. The company director has asked you to design the new system to assign seats for each trip of the 50-seater ferry, which covers the route from Penang to Langkawi and back daily. The upper deck of the ferry is reserved for business class passengers and can accommodate 10 people. The main deck of the ferry, the economy class can accommodate 40 people. Assume the company has at least 8 ferries - each with a different Ferry ID, which travel at one-hour intervals from 10 am to 5 pm daily.
SECTION A : BASIC REQUIREMENTS OF THE SYSTEM
1. Main Menu
Your initial program design should display the following menu alternatives:
FERRY TICKETING SYSTEM
P – to Purchase Ticket
V –to View Seating Arrangement
Q – to Quit the system
2. Submenu
The following submenu will be displayed when P is selected:
PURCHASING MODULE
B – to purchase ticket for Business class
E – to purchase ticket for Economy class
M – to return to Main Menu
3. Assigning Seats
If the person types B, then your program should assign a seat in the business class (seats 1-10). If the person types E, then your program should assign a seat in the economy class (seats 11 - 50).
4. Boarding Ticket
Your program should then print a boarding ticket indicating the person’s name, seat number, whether it is in the business or economy class of the ferry, Date and time of departure, Source and Destination of the trip and Ferry ID.

5. Seating Chart
Use single-scripted array to represent the seating chart of the ferry, indicating the availability of the seats within each trip of the ferry. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of the array to 1 to indicate that the seat is no longer available. Your program should never assign a seat that has already been assigned.
The Ferry ID will be requested when V is selected from the main menu and the seating arrangement for that ferry will be displayed in a tabular form, e.g.
*************************************************************
* Ferry ID : 007 Date: 19 Sept 2005 *
*************************************************************
* BUSINESS CLASS *
*************************************************************
* 1 * 1 * 1 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* ECONOMY CLASS *
*************************************************************
* 1 * 1 * 1 * 1 * 1 *
*************************************************************
* 1 * 1 * 1 * 1 * 1 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
* 0 * 0 * 0 * 0 * 0 *
*************************************************************
6. Alternative seating
When the business class is full, your program should ask the person if it is acceptable to be placed in the economy class (and vice versa). If yes, then make the appropriate seat assignment. If no, then print the message “Next trip leaves in 1 hour”.

Thank you thines01
actually as you said, i replaced and fixed the error on line 6.
now i have problem in line 14.This is the output of the compiler:
subMenu();
^
symbol: method subMenu()
location: class FerryTicketingSystem
1 error

and then at then end of compiling i have another error that said :
--------------------Configuration: <Default>--------------------
Error: Could not find or load main class FerryTicketingSystem

Process completed.

this is for general output.

And can you please explain more about "level" class and make example for me.
thank you very much
Regards

Thank you some much from thines01!
You are so clever and awsome. thank you very much.
and thank you from NormR1 for reply.
now all of the problems solved and the program build so successfully.
I have a problem in section 3,4,5,6 and i don't have any good idea to do them.
Can i know your idea and opinion how to do them?!

I wrote these codes with my bad idea for section 3,4,5,6.
But don't pay attention to my codes and my idea! :D
i don't think it is really good and work.
These are my codes for those sectios:

My dear NormR1, i'm so sorry for too many questuin i asked!
this is my first year of level one in bachelor of IT(Information Technology).
I hava a subject that it is java programming. i try my best for this subject, my lecterur is not good, and she didn't teach this programming language as well.
I tried my best to learn it and do it! but really i become confused! i know this language, but i don't know what should i do exactly!
If it is possible for you, please help me to finishing this program, if not, thanks for your help and i don't want to disturb you any more my dear! :(
Regards

You need to ask specific questions if you want help.
Take the sections one at a time. Design the code for one section, write it and try to get it to compile and execute. When you have problems or questions post them here.
